How does it work?

The Eco safe choice

Pipefreezing method?

Pipefreezing involves the use of Liquid nitrogen in the controlled formation of a solid ice plug within the pipeline. Once the freeze is achieved the plug has the capability to withstand very high differential pressures and provides a reliable isolation that is extremely effective, allowing alterations to be completed without a full drain down.

The Benefits of Pipe Freezing

Pipe freezing is widely acknowledged as a safe, reliable and highly cost effective method of temporary pipeline isolation and offers a number of major benefits some of which are:-

• No need to drain down systems, thus avoiding costly and time consuming venting procedures

• No need to arrange for the bulk transfer/storage of fluids

• Cuts losses of expensive liquids, such as treated water and system inhibitors.

• Overcomes the problems of handling hazardous materials and enhances safety when working on lines containing contaminated or volatile liquids.
